7. Question 307 · 382 in bank

   When redistribution is configured between OMP and BGP at two Data Center sites (DC) that have Direct Connection Interlink, which step avoids learning the same routes on WAN Edge routers of the DCs from LAN?

   • ASet down-bit on WAN Edge routers on DC1
   • BDefine different VRFs on both DCs
   • CSet OMP admin distance lower than BGP admin distance
   • DSet same overlay AS on both DC WAN Edge routers

   Show answer

   Answer: D

   Explanation

   By default, OMP is transparent to BGP even if propagate-aspath configured. overlay-as is a feature that prepends AS specified as a parameter of this command to BGP AS_PATH attribute of routes exported from OMP to BGP. If you configure the same overlay AS number on multiple devices in the overlay network, all these devices are considered to be part of the same AS, and as a result, they do not forward any routes that contain the overlay AS number, hence routing loop will be prevented. As Hoon said, answer D
